“…Similar work using a poly(3-hexylthiophene) (P3HT) donor block and C 60 -grafted PMMA [78] shows improved photoluminescence quenching compared to a simple blend of P3HT and phenyl-C 61 -butyric acid methyl ester (PCBM), indicating better exciton dissociation, although photovoltaic cells made from such material demonstrated only a modest photovoltaic effect. Recent work by Tao et al [79] using P3HT as the donor and perylene as the acceptor, and by King et al [80] using PvTPA-perylene, also demonstrate phase separation of the blocks, although the PV effect is decidedly modest in both cases. Zhang et al [72] synthesized a P3HT-b-perylene diimide acrylate (P3HT-b-PPDA) block copolymer, taking advantage of the high carrier mobility in both phases.…”

Nanostructures generated from block copolymer self-assembly enable a variety of potential technological applications. In this article we review recent work and the current status of two major emerging applications of block copolymer (BCP) nanostructures: lithography for microelectronics and photovoltaics. We review the progress in BCP lithography in relation to the requirements of the semiconductor technology roadmap. For photovoltaic applications, we review the current status of the quest to generate ideal nanostructures using BCPs and directions for future research.

“…Segalman et al 132 later prepared a comparable poly(3-hexylthiophene)-block-poly(n-butyl acrylate-stat-acrylate perylene), interestingly via click chemistry. They examined the link between order and the effect on device properties using AFM and transmission electron microscopy (TEM), utilizing solvent annealing to order their spin cast films.…”

A simple overview of the methods used and the expected benefits of block copolymers in organic photovoltaic devices is given in this review. The description of the photovoltaic process makes it clear how the detailed self-assembly properties of block copolymers can be exploited. Organic photovoltaic technology, an inexpensive, clean and renewable energy source, is an extremely promising option for replacing fossil fuels. It is expected to deliver printable devices processed on flexible substrates using high-volume techniques. Such devices, however, currently lack the long-term stability and efficiency to allow organic photovoltaics to surpass current technologies. Block copolymers are envisaged to help overcome these obstacles because of their long term structural stability and their solid-state morphology being of the appropriate dimensions to efficiently perform charge collection and transfer to electrodes.

“…These polymers consist of typical donor-type backbone and PDI side chain. Examples of donor-acceptor polymer architecture including polymers with PDI in the side chain were reported [23][24][25][26][27][28][29]. The results of BHJ OPV based on these polymers show the efficiency typically much less than 1%.…”

The Effect of Aromatic Diimide Side Groups on the π-Conjugated Polymer Properties

Abstract:The presented study describes the method for the synthesis and characterization of a new class of conjugated copolymers containing a perylenediimide (PDI) and naphthalene diimide (NDI) side groups. The main conjugated backbone is a donor-acceptor polymer poly[3,6-carbazole-alt-5,5-(4 ,7 -di-2-thienyl-2 ,1 ,3 -benzothiadiazole)] containing thiophene and carbazole as donor units and benzothiadiazole as an acceptor unit. The presented compounds were synthesized in a multistep synthesis. The polymerization was carried out by Suzuki or Stille coupling reaction. Redox properties of the studied polymers were tested in different conditions. Electrochemical investigation revealed independent reduction of the main polymer chain and diimide side groups. UV-Vis spectroscopy revealed the overlap of two absorption spectra. The difference between the electron affinity of the polymer main chain and that of the diimides estimated electrochemically is approximately 0.3 eV.
